Therefore, within each region file there is a mini-filesystem, which handles variable-size compressed chunks. A simple fixed-size system, as used in 2.2, cannot work. The main complication with the new format is that chunks no longer have the same size – some compress more, some less. But Deflate is so ubiquitous and so easy to use – it is good enough for us at the moment. There are more modern and better compression algorithms – like Zstandard, which is both faster and provides better compression. Deflate has been the workhorse of compression for many decades now.

Standard deflate compression (the same as used by zip format) on the resulting RLE-compressed data Deep down you get hundreds and hundreds of the same granite/basalt blocks, up in the air it’s all air, obviously. Block values are more repeatable in horizontal directions than in the vertical. This is to maximize gains from the RLE scheme. Only if the count is too large to fit in the light section (4 bits), a separate byte is allocated for the count.Īdditionally, the order of blocks storage is changed from how they are kept in memory. The count value is stored in the “light” section of the block data, so it doesn’t take any more space than the raw, uncompressed block (light value does not have to be saved – it is generated anyway). RLE compression stores the value of the block followed by the repeat count, instead of storing all blocks separately. RLE compression to exploit the repetitive nature of the world blocks.

The chunks within the region file are compressed using a two-step process:

The new format divides the world into regions of 16×16 chunks (where chunk is 16x16x256 blocks). It is a more complex system compared to the old one, which stored raw block values divided into constant-size chunks. I told you about it in one of the previous posts. I think the most important change in 2.3 is that it uses a new, compressed storage format for the world files. As pistons are moving blocks, they trigger motion sensors in 2.3 – so the blocking no longer works. Some of you have been complaining that motion sensors detecting movement of projectiles, pickables and moving blocks (a new feature in 2.3) broke their builds, because they were using pistons to block off visibility of sensors.
Santa in survival craft demo update#
We will need to wait for the stores to approve the update – hopefully only about a day. Reduced number of pickables created by explosions.Reduced chance of spawning of many creatures of the same type.

Hammer makes appropriate material sound when used to make furniture.Fixed depth clipping when crouching near a wall.Fixed glitches and improved wooden ladder.Crouching deaths in low spaces fixed, general crouching improvements.Fixed broken uploading/downloading of 2.3 worlds.I will very soon release a bugfix update for the 2.3 release.
